This variant is denoted VHL c.578A>G at the cDNA level, p.Asn193Ser (N193S) at the protein level, and results in the change of an Asparagine to a Serine (AAT>AGT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. VHL Asn193Ser was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Asparagine and Serine share similar properties, this is considered a conservative amino acid substitution. VHL Asn193Ser occurs at a position that is not conserved and is located within the beta-domain (Yuen 2009). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available evidence, it is unclear whether VHL Asn193Ser is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
